What is an ignition interlock device?

An ignition interlock device is an in-car alcohol breath screening
device that prevents a vehicle from starting if it detects a
blood alcohol
concentration (BAC) over a pre-set limit. The device is located inside
the vehicle, near the driver’s seat, and is connected to the engine's
ignition system.

Smart Start’s ignition interlock system effectively separates drinking
from driving. It combines advanced technology, accurate monitoring and
responsive, flexible reporting. At the heart of Smart Start’s solution is
the SSI-1000® – a state-of-the-art handheld breath-alcohol monitoring
device electronically connected to the vehicle ignition. Alcohol-specific
and similar in size to a cellphone, the SSI-1000 was developed using
fuel-cell sensor technology for reliability and ease of operation. Smart
Start pairs this proven device with proprietary Smartrac® and SmartLog®
software. This makes it easy for drivers to use, and allows the interlock
program and reporting to be customized to a particular jurisdiction.

The SSI-1000, developed exclusively by Smart Start, reflects
state-of-the-art interlock technology. Multiple design features make the
device difficult to defeat. The built-in microchip records all test
results, engine starts and stops, disconnections and tampering for later
review.
